This practice is much more common with low hydrogen electrodes, since the core wire melts up inside the fluxcoating.
这种做法较为普遍，低氢焊条，因为融化的核心线内的通量涂层。
2
The effect of the flux of reactive gas on coating is analysed.
分析了反应气体流量对涂层的影响；
3
The results show that the realizing flux-wall to guid transfer form of metal droplet is a prerequisite to the fine usability of double coating electrode.
